# Math Help - Zero Factor Property HELP

1. ## Zero Factor Property HELP

So were on the chapter where we factor polynomials by reversing the process and using zero factor property. Here are the questions with my answers...can someone check for me??

1. 12x^2=8x

12x^2-8x=0
4x(3x-2)=0

2. x(3x-2)-7(3x-2)=0

(x-7)(3x-2)=0
x-7=0 3x-2=0

3. x(x+9)=2(x+9)
x(x+9)-2(x+9)=0
(x-2)(x+9)=0

Did I do these correct?
